I'm a sky watcher and it's important to know that to know if you have a chance at seeing the Aurora. I have an app that alerts me if it's high at my location. I lived further north than Moscow for over a year and never saw it as plainly as I've seen it in this past year over the Pacific Northwest. And it's happening so often that I noticed that I feel crappy every time, so that's how it came to matter to me 😅
